Advanced Functional Labs

Test Don’t Guess. Get Real Answers.

Most conventional labs are designed to detect disease—but functional medicine labs help us catch dysfunction before it becomes a diagnosis. They give us deeper insight into how your body is functioning on a cellular level, allowing us to uncover root causes and create truly personalized care plans.

At Vital Source Functional Medicine, we use advanced lab testing to explore gut health, hormones, detox capacity, nutrient status, blood sugar, inflammation, and more. These tests allow us to move beyond symptom management and into meaningful healing.

Why Functional Labs Matter

Symptoms don’t tell the whole story—but the right testing can. These tools help us stop guessing, track progress, and uncover hidden patterns that are often missed in conventional care. Most importantly, they allow us to tailor your protocol with precision and purpose.
